Food and time. There are no secrets to gaining mass and you need to be more patient and stop asking questions about every minute thing.

You should focus on two things: technique and spending time in the kitchen/table.

yeah I been working on my techniques lately. I think that is my problem. I am a bit impatient. I know people would kill for the weight gain I received in 6 months from 170ish to 200-05 as of now but I feel like I am no where close to my goal..but I should learn how to take baby steps

I just been trying to figure out the science behind bodybuilding. I mean I know its time, food, and lifting heavy. for bulking and cutting is opposite except the time part, lol.

But what is the real science behind it. Like for instance is there a real difference in lets say, 2 ectomorphs have same genetics, life style, weight, lifting style and consume the same exact calories; lets say, 4000 calories. What is the science behind BB if one goes heavy 4-6 reps and stays on that weight until he reaches 8-12 reps and adds weight until he can hit 4-6 reps with the right weight
vs
someone who does 4-6 reps next exercise add more weight rather then waiting till he can do 8-12 reps and so on and so on. But always staying around the 4-6 rep
